Happiness Chemicals: Daily Rituals to Activate Joy Naturally is a playfully illustrated book that will teach you how to stimulate your four happiness chemicals from within: dopamine, serotonin, endorphin and oxytocin. Read one page a day and happiness will follow! We all live with chemicals inside us that can change our moods dramatically when activated. With the help of this book you'll be able to activate your happiness chemicals whenever you need a pick-me-up. First you identify which chemical you feel you need most: Serotonin: the mood stabiliser Dopamine: the reward chemical Endorphin: the pain killer Oxytocin: the love hormone. Then all you have to do is turn to a page, follow the prompt and you'll get high off your own supply. Backed by science, each activity includes 'what we know' and 'what to do'. They are fun and achievable activities like listen to music, go for a hike or hug a friend, making these chemicals easily accessible.
